TL431/TL432ADJUSTABLE PRECISION SHUNT REGULATORDescription Pin Assignments The TL431 and TL432 are three terminal adjustable shuntregulators offering excellent temperature stability and outputcurrent handling capability up to 100mA. The output voltagemay be set to any chosen voltage between 2.5 and 36 voltsby selection of two external divider resistors.The devices can be used as a replacement for zener diodesin many applications requiring an improvement in zenerperformance. Diodes’ TL431 has the same electricalspecifications as the industry standard ‘431 and is availablein 2 grades with initial tolerances of 1% and 0.5% for theA and B grades respectively.
